(GRANTED UNDER THE ACT 0F MARCH 3, 1883, AS AMENDED APRIL 30, 1928; 3700. G. 757) The invention described herein may be manufactured and usedby or for the Government for governmental purposes, without the paymentto me of any royalty thereon.

5 The subject of this invention is a gun mount and carriage and is acontinuation in part of application Serial No. 480,670, led

September 9, 1930. v

In the prior application there is disclosed 1 a combination gun mountwhich is designed primarily as a light field artillery weapon on amobile carriage but is also capablefof being emplaced as a semi-fixedplatform for the purpose of delivering lire at aerial targets.`

In the present ap lication there is shown a further method of othtransportation and emplacement, the elements provided for em- 20placement of the gun mount proper being also adapted to emplace thecarriage.

The invention consists essentially in providing a prime mover adaptedfrom a standard automobile chassis. The chassis carries a pedestal gunmount, a hoist for lowering and raising the mount to and. from theground, and means whereby it may be emplaced when the gun is to be firedfrom the chassis as a platform. so Withthe foregoing and other objectsin view, the invention resides in the novel ar- ,.rangement andcombination of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed may be made within thescope of what is claimed without departing from the spirit of theinvention.

A practical embodiment of the invention is illustrated in theaccompanying drawings, wherein:

Referring to t e drawings by numerals of reference:

There is shown a vehicle 5 which is a standard commercial automobilechassis preferably having a four-wheel drive. A. pedestal 7 gun mount 6is placed on the frame 7 of the chassis directly above the rear wheelsand may be secured to the frame in any convenient manner. The gun mount6 is identical with the one shown in the original application for patentand for the purpose of the present description it is sufiicient toidentify only the sockets 8 that are provided at the four corners of thebase of the pedestal to receive the outriggers 9. 8

The frame 7 carries a front jack 10, a rear jack 11 andltwo side jacks12-12 positioned intermediate the length of the vehicle. The side jacks12 have apspecialmounting (Fig. 10) each being associated with a socketmems ber 13 adapted to receive one of the outriggers 9. The jacks 12include a pair of spaced arms 14-14 embracing the socket member 13 andattached thereto adjacent the upper end y by means of a pivot pin' 15.In the travelling osition the jack is swung up`and over the ame and heldin an elevated position that is convenient for subsequent lowering bymeans of a pin`16 passing through the jack and a bracket 17 on thesocket member. In the emplaced position-with the jack lowered onto theground the in 16 is reemployed and passed through e jack and an aperture18 irxclihe socket member 13 to immobilze the wo l Onthe under side ofthe socket member there is pivotally secured a rod 19 adjustable as tolength by means of a turnbuckle 20. In the emplaced position the freeend of the rod is attachable to a bracket 21 on the under side of theOutrigger, and serves to tie the outrigger to the vehicle. In thetravelling position the rod 19 is swung up and connected to a short link22 on the upper end of the socket member.

On each corner of the rear end of the chassis (Figs. 1 and V9) framethere is a bracket 23 pivotally carrying an adapter 24 forming a socketfor receiving one of the outriggers 9. These adapters conform to thesockets 8 on the forward side of the base of the pedestal mount asclearly shown in Figs. 2, 3, and 5, so that they may receive thecorresponding outrigger A rod 25, adjustable as to length by means ofthe turnbuckle 26, is attached to the frame and is securable to thelower portion of the adapter. When the Outrigger is fastened to theadapter, the rod 25 serves to tie the Outrigger to the vehicle.

Referring to Figs. 1 and 9 a standard 27 is mounted centrally on therear end of the chassis frame, and carries a hoist 28 which may belifted out and removed when the gun is to be fired from the vehicle asshown in Fig. 3. The cable 29 of the hoist is engageable with an eye 30on the gun whereby the gun mount 6 is lowered and raised to and from theground.

In the travelling position a pair of outriggers are disposed on eachside of the vehicle (Figs. 1 and 6). The forward ends of the outriggersare slidably received in a guide block 31 on the running board 32 andthe rear ends are supported by an arm 33 carried by the vhoist 28. Asseen in Figs. 7 and 8 the two arms 33 constitute a yoke whose hub isformed by half-bearings 34 on the arms 33. A tongue and grooveconnection 35 between the half-bearings serve to support the arms on thehoist and permits ready removal of the individual arms 'from the hoist.

The outriggers fit into a recess 36 in the outer extremity of the arm 33and are confined by a. pivoted strap or cover 37 which may be latched inany suitable manner.

In Fig. 1, there is shown a trailer comprising a bogie 38 which may beused to carry the pedestal gun mount 6 (Fig. 11) in the mannerspecifically described in the original application for patent previouslyreferred to. In employing the trailer a pair of the outriggers 9 aresecured to the gun mount and employed as a draw-bar for connection v tothe prime mover. The remaining two outriggers are vavailable tO ,form aplatform underneath the mount when it is to be fired without removingthe bogie 38.

By providing several methods of transportation and emplacement of thegun mount,

the weapon may be employed against both ground and aerial targets. It iscapable of being rapidly moved on good roads andinasmuch as endlesstracks have been adapted to the pneumatic wheels of the commercialtruck, they can be carried on the frame 7 and applied when it isnecessary to travel oi of the road. While guns have heretofore beenmounted on prime movers that could be emplaced by means of'jacks andoutriggers, the

particular arrangement provided was not conducive to rapid manipulationof the emplacing means and stability was seldom obtained.
